SECTIONAL RAILWAY-RAIL.

Specification oi' Letters Patent.

Patented April 20, 1909.

Continuation of abandoned application, Serial No. 301,325, filed February 15, 1906. This application iled February 3, 1908. Serial No. 414,002.

To all whom 'it may concern:

Be it known that l., CAMPBELL Atlases, a citizenof the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Sectional Railway-Rails, of which the following a specification, containing' a full, clear, and evact description, reference being` had to the accompanying drawings, forming a part hereof.

My invention relates to impro f'eulents in sectional rails, and particularly to a sheet metal or steel rail; and this application is liled as a substitute for my prior abandoned application, which was filed by me on Feta-1n ary 15th, 1906, Serial No. 801.325.

The object of my invention is the improvement of the construction of a sectional rail, whereby the adjoining sectionsl of each two rails are so assembled as to form practically a continuous rail.

A further object of my invention is to so construct the sections of a rail as that said sections may be assembled to form a continuous'rail without the use of bolts, or similar fastening devices.

1With these and other objects in view, the invention consists of certain other novel con structions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying' drawings, Figure l represents a fragmentary perspective view of the adjoining ends of two rails constructed in accordance with the present invention; F ig. 2 is a fragmentary perspecth e view of the base plate orbar of the rail; Fig. 3 is a transverse sectional view; and .if g. -lis a similar view of another embodiment of the rail.y

' Referring t0 the drawings by nurnei'als--- l l designates the base plate or bar, constituting the base flange of the rail. rlhe base l has its longitudinal edges bent upward for forming longitudinal extending flanges QWQ. These flanges are preferably bent inward for forming a substantial dove-tailed socket, within which is positioned the lower edge of the vertical upright or strengthening section orbar, or they may be bent to form a rectangular socket or groove parallel with the base plate, as shown in F ig. 2. The section 3 is preferably positioned in the middle of t-he base plate 1, and between the two side sections or bars 4.-4. Each of the sidematerial, as. for instance, steel, so that it may be sprung into position if desired, as hereinafter described. The lower edges 5 of the middle 0r central section and the side sections t are flat; or, in other words, are formed parallel with the upper surface of the base plate l so as to rest snugly against said surface when in their normal assembled position, Fig. l; or they may be bent so that their flat edges snugly fit into the longitudinal groove in the base plate, as shown in Fig. The upper edges 5 of said sections 3 and el: are similarly constructed, whereby they rest .flat against the inner surface of the dovetailed groove of the tread section 6 of the rail. Each of the tread sections 6 is preferably provided at one end with a substantially V-shaped cut out or notched portion 7, or other indentation, and at its opposite end with a similarly constructed projection S. Each two cut out portions 7 and extensions 8 form substantially a continuous tread, which is engaged by the wheels passing along the rails, thereby preventing any hammering or other undesirable effects that are experienced when employing ordi,- narily constructed rails, which rails are provided with abutting ends formed at right angles to the side of the rails.

lhe adjoining ends of the sections of each of two rails are not positioned in transverse alinement, but the abutting ends of the seetions are each positioned in dilierent transverse planes, thereby placing each joint so as to receive the weight of the load at a different time from that of the other joints. By this positioning of adjoining ends of the like sections, I form a continuous rail which has no joints which will give under a load. Of course it is to be understood that the sections etupon one side of the rails do not have their adjoining ends positioned in the same transverse plane with the adjoining ends of the sections 'l upon the opposite side thereof.

In Fig. l, the ends of two of the sections upon one side abut. as at 10, while the ends of the side sections upon the other side of the rail engage at 1l. The middle sections 3 engage, as at l2.

In Figs. l and 2:3, the upper edges of the middle section 3 and the side sections t and it are positioned within the dove-tailed grooves of the tread section (i, which groove is formed by the downwardly extending sections 4 is preferably formed of resilient l flanged edges 13. The inner surface of the it i ai flanges 13 eXtend inwardly from the outer edges, thereby forming surfaces which are engaged by the outer surfaces of the side sections.

As all of the sections ot the rail, and particularly the side sections, are formed of sheet metal, said side sections may be sprung into the dove-tailed grooved portion of the base section and the tread section, :formed between the flanged edges of said sections, or the lower portions of the middle and side sections may be positioned within the grooved portion of the base section, and then the tread section driven longitudinally upon and over the upper longitudinal edges oit said middle and side sections for assembling all of the sections.

ln the embodiment illustrated in Fig. et, l have shown the base section lelprovided with longitudinally extending grooves, within which grooves the lower portion of the middle section 3 and the ,side sect-ions l ot' t-he rail are positioned. rll'he tread section 15 is also provided with longitudinally extending grooves for receiving the upper portions or longitudinal edges o1 the upright or vertical sections 3 and 4; while the middle, longitudinally extending grooves ot the and tread sections are formed in a vertical plane, the side, longitudinally extending grooves in which the side sections Ll are positioned, are inwardly inclined for receiving the upper and lower edges ot the spring side sections el.

By reason of the peculiar structure ot' my sectional steel rail, transverse fastening means, as for instance the ordinary bolts and lish plates, are obviated, although, ir" in some cases it is found desirable, they may be employed.

From the foregoing, it will be obvious that l have provided a sectional rail capable of sustaining a greater weight than the ordinary solid rail, and having greater rigidity t-han a solid rail ot' equal weight.

The material ot which the sections are termed are of sufficient resiliency to permit a slight yielding of the rail when necessary tor preventing any `jar as the cars pass over the same.

l claim l. A continuous rail, comprising a web portion formed ot a plurality of plates, the upper and lower edges ot' the outer pair oit' plates being bent outward away from the center plate, a tread portion detachably applied to the upper ends of the plates forming the web, and a base portion detachably applied to the lower ends of the plates forming the web portion.

2. A continuous sectional rail, provided with removable abutting tread sections, one

detachably applied to the lower edges of said plates.

3. A rail, provided with a removable tread section, said tread section provided at one end with a tl-shaped recess, at its opposite end with a V-shaped extension, a plurality of plates forming the web ot the rail, and a base section detachably applied to the lower edges of said plates.

el. A rail, comprising` a base section, a tread section, side sections positioned between said base and tread section, and a separat-e intermediate section interposed between said side sections.

A rail, comprising a base and a tread section, resilient side sections positioned between the said base and tread section, meanS for holding all of said sections in an assembled position, and a separate plate interposed between said side sections and engaging said base and tread sections.

G. A sectional rail, comprising a base and a tread section, each ot said sections provided with longitudinally eXtending tlanged edges, a middle section and side sections positioned between the base and tread sections and having their upper and lower edges positioned between the flanged edges of said tread and base sections, respectively.

7. A continuous rail, comprising abutting` base and tread sections, side and central sect-ions positioned between said base and tread sections and having their adjoining ends positioned in different transverse planes, and flanges formed on the base and tread sections and engaging` the top and bottom edges of the side sections.

S. A sectional rail, comprising sheet metal resilient side sections, a base section connecting the lower portion of said side sections, a tread section connecting the upper portions of the side sections, and a separate plate positioned between the side sections.

9. A sectional rail, comprising a base section, a plurality ot resilient plates forming the web ot' the rail, and being detachably arranged on the base section, and a. hardened metal tread section detachably applied to the upper edges of the plates forming the web of the rail.

ln testimony whereof, l have signed my name to this specification, in presence of two subscribing witnesses.
